A multiscale analysis and finite element method are proposed to study the interaction of nanotubes and matrix at the nano-scale near a crack tip. The effects of the length and chirality of single walled carbon nanotube (SWNT) in a polymer matrix in presence of van der Waals (vdW) interaction as inter-phase region on the fracture behavior were studied. It was found that the length and chirality has a significant effect on stress intensity factor of nanocomposites.
